Improvement through training: A criterion in test validation

Abstract

This study was undertaken to decide about an adequate criteria which may be adopted in validating aptitude tests used in Naval Training Schools. Three criteria- final score, residual gain and crude gain, were compared. The final decision regarding the choice of criterion was primarily based on logical considerations. Residual gain, which measures that aspect of final score which is uncorrelated with initial status and thus removes some of the non-appropriate variance from the criterion and further overcomes the inconsistencies which crude gain presents was found to be a more realistic criterion
